In case you had somehow overlooked it, today is the 150th anniversary of the publication of Charles Darwin’s “On the Origin of Species,” the scientific landmark that reshaped the way we see the natural world—and which religious extremists rail about to this day.

People For the American Way Foundation has a long history of opposing religious belief being taught as fact in public schools, and we’ve worked hard to defend classrooms against religious doctrine dressed up as science.

To learn more about the many ways creationists have tried to push Darwin out of public schools, check out our Creationism Timeline as well as Right Wing Watch’s coverage of creationism. And don’t forget to raise your glass tonight to wish “On the Origin of Species” a very happy birthday.
